Open-close body driving device

Abstract

An open-close body driving device includes a motor configured to open and close an open-close body included in a vehicle and a controller controlling a movement speed of the open-close body driven by the motor. The controller is configured to move the open-close body at a normal speed based on a vehicle-side operating signal output by operation of an operating switch installed on the vehicle and at a speed lower than the normal speed based on a remote operating signal output by operation of a mobile device. The controller is configured so that in a shutting region having a predetermined dimension from a fully-closed position toward an open side, closing movement of the open-close body based on the remote operating signal is slower than closing movement of the open-close body based on the vehicle-side operating signal.

The invention claimed is: 
     
       1. An open-close body driving device comprising:
 a motor configured to open and close an open-close body included in a vehicle; and 
 a controller controlling a movement speed of the open-close body driven by the motor, wherein 
 the controller is configured to move the open-close body at a normal speed based on a vehicle-side operating signal output by operation of an operating switch installed on the vehicle and at a speed lower than the normal speed based on a remote operating signal output by operation of a mobile device, and 
 the controller is configured so that in a shutting region having a predetermined dimension from a fully-closed position toward an open side, closing movement of the open-close body based on the remote operating signal is slower than closing movement of the open-close body based on the vehicle-side operating signal. 
 
     
     
       2. The open-close body driving device according to  claim 1 , wherein the controller is configured to move the open-close body at a speed lower than the normal speed based on input of both the remote operating signal and a signal indicating that an ignition switch of the vehicle is off. 
     
     
       3. The open-close body driving device according to  claim 1 , wherein
 the controller has a speed control pattern of closing movement in relation to a position of the open-close body and controls speed of the closing movement of the open-close body based on the speed control pattern, 
 the speed control pattern includes multiple patterns including at least a normal speed control pattern and a low speed control pattern using a lower speed than the normal speed control pattern, and 
 the controller closes the open-close body using the normal speed control pattern based on the vehicle-side operating signal and closes the open-close body using the low speed control pattern based on the remote operating signal. 
 
     
     
       4. The open-close body driving device according to  claim 3 , wherein the normal speed control pattern includes a constant speed section in which the open-close body closes at a constant first speed, a deceleration section that is set at a closed side of the constant speed section to reduce speed of closing movement of the open-close body from the first speed, and a constant low speed section that is set between the deceleration section and the fully-closed position to close the open-close body at a constant second speed that is lower than the first speed. 
     
     
       5. The open-close body driving device according to  claim 4 , wherein the low speed control pattern is a pattern in which speed of the constant low speed section in the normal speed control pattern is lower than the second speed. 
     
     
       6. The open-close body driving device according to  claim 5 , wherein the low speed control pattern is a pattern in which a starting position of the deceleration section in the normal speed control pattern is shifted toward the open side. 
     
     
       7. The open-close body driving device according to  claim 1 , wherein
 closing movement of the open-close body based on the vehicle-side operating signal includes a constant speed section in which the open-close body closes at a constant first speed and a constant low speed section in which the open-close body closes at a constant second speed that is lower than the first speed, and 
 closing movement of the open-close body based on the remote operating signal includes a constant speed section in which the open-close body closes at the constant first speed and a constant low speed section in which the open-close body closes at a constant third speed that is lower than the second speed. 
 
     
     
       8. The open-close body driving device according to  claim 7 , wherein
 the closing movement of the open-close body based on the vehicle-side operating signal further includes a deceleration section in which speed of the closing movement of the open-close body is reduced from the first speed to the second speed, 
 the closing movement of the open-close body based on the remote operating signal further includes a deceleration section in which speed of the closing movement of the open-close body is reduced from the first speed to the third speed, and 
 a starting position of the deceleration section in the closing movement of the open-close body based on the remote operating signal is shifted toward the open side from a starting position of the deceleration section in the closing movement of the open-close body based on the vehicle-side operating signal.
